Lenses for Puerto Galera Trip

Yesterday, 02:53 AM

Am going to Puerto Galera at the end of February for one week
I have a Panasonic GX7 and am planning to dive mostly with the Olympus 60mm.
I will also be taking a Sony RX100 IV with wet lenses for video
I also have the 14-42mm kit lens, the Panasonic 7-14mm with wide angle port and the 8mm fisheye however I wonder if I should even bother taking those lenses with me?
Any help appreciated

Encoding 4K videos

28 November 2015 - 03:47 AM

I have been playing recently with both the Panasonic LX100 and the Sony RX100 IV

Both cameras shoot 8 bit 100 Mbps H264 video files. The panasonic codec appears more advanced but the video settings are pretty basic so most of the detail is lost.

Anyway I uploaded some sample files converted to prores and then coded them in H265, the resulting files are pretty small and have outstanding quality at 25 Mbps when I play them on Minix.

However when I tried to upload to youtube I got an error as H265/HEVC is not supported.

Has anyone found a (mac) application that can encode VP9? No product that I have supports it and encoding back to H264 means loosing lots of information from 100 -> 32 mbps?

It seems like the whole 4K situation is pretty undeveloped and the resulting files in 1080p look worse than my old HD encodes??

New Nauticam Bayonet system for wet lenses

14 November 2015 - 11:41 AM

I received the new parts from Nauticam and I have put some images on my blog


It looks very promising for those interested in the new Nauticam range



First comparisons between RX100 and A7 picture profiles

08 November 2015 - 12:41 PM

I have done a few tests on the profiles and settled for what I personally like




There are some examples there but I will take more in the future


My summary is that without a recorder you have some options that with no or minimum correction in post perform pretty well.


S-log2 for me does not work at 100 Mbps but I believe that with an external recorder this can product incredible results

Sony RX100 IV/A7 Picture Profile

13 October 2015 - 12:16 PM

I am playing with the picture profile to get something that is good straight from camera with my RX100 mark IV

The profile PP3 looks ideal it has the following parameter

Gamma ITU709

Color Mode Pro (not sure what that is)


I have set knee to auto 95% mid drop


The only doubt I have is the detail setting that seems to control sharpenss. I have left it to default but it has many options that I don't quite understand.

Anybody has got a clue??
